Changes to:
objfmt interface: added parameter to directive() for sections access.
section interface: moved start to be present for all section types.
basic optimizer: add section start to offset determination.
(much of the section start changes are due to the need to make sure offsets
don't end up being optimized into byte-sized offsets that can't be relocated).

- preproc initialize function
- parser parse function (to pass to preproc initialize)
so that the preprocessor has a clue what file it's in.

Or at least it has begun. At this point it can only handle:
%define
%if*def
%el*def
%else
%endif
%include (to some degree; needs a lot of thought, but recurses fine)
and replacing simple %defines (like %define foo bar)
And like all code, it's probably horribly inconsistent about variable
names, etc. We'll wash it later.

function gets a FILE *, and it's the only function that can write to a file.
The object file is thus not opened until AFTER parsing and most error checking
is complete. Necessitated adding a special case for the dbg object format
because it needs to output to the "object" (debug) file from essentially every
function. Added a global (debug_file) to support this.

just assigned the pointer: but the symrec is deleted (if it's not in the symbol
table) when the expr is deleted. Thus, we need to create a copy of the symrec
instead of just reusing the same value if it's going to be deleted later. This
trickles down to objfmt to copy the objfmt-local data.

This is because calc_len may want to know the current bytecode's offset (eg for
determining relative displacement length).

"index". This fixes some problems with assumptions made by various parts of
the code that are invalidated when the line number doesn't always increase (eg.
when the NASM %line directive is used).
Speed fixes are needed to the implementation of the line_* functions in
globals.c before this is finished.

into the optimizer stage, where it belongs. Naming has changed, but most
implementations have not been brought up to date to do what they say they
do.

is done in the grammer causes 1 shift/reduce and 1 reduce/reduce conflict, but
yacc's default resolution gives correct results, and as the generated grammer
is smaller this way than specifically handling each prefix, we do it this way.

wrong (the ModRM byte definitely must be kept), but it had a memory leak too
(it just freed the ea without calling expr_delete())!
